//Set the database connection 
    ($GLOBALS["___mysqli_ston"] = mysqli_connect('localhost', 'root', 'chethan')); 
    ((bool)mysqli_query($GLOBALS["___mysqli_ston"], "USE " . 'bigdata')); 
    //select all rows from the main_menu table 
    $result = mysqli_query($GLOBALS["___mysqli_ston"], "select id,title,parentid,link from main_menu"); 

    //create a multidimensional array to hold a list of menu and parent menu 
    $menu = array(
     'menus' => array(),

    ); 

    //build the array lists with data from the menu table 
    while ($row = mysqli_fetch_assoc($result)) { 
     //creates entry into menus array with current menu id ie. $menus['menus'][1]
